Answer:
a. Maximum= 27, minimum= -5
b. Maximum= 19, minimum=-37
Step-by-step explanation:
We have the function . Since the function correspond to a line, then the maximum and minimum values of the function over an interval are in the endpoints of the interval.
Observe that if the line has negative slope then the minimum value is in the right endpoint. If the line has positive slope the minimum value is in the left endpoint of the interval.
The function f(x) has slope m=8. Then
a. the minimum value of f(x) in the interval [0,4] is reach when x=0, and the minimum is and the maximum is
b. the minimum value of f(x) in the interval [-4,,3] is reach when x=-4, and the minimum is and the maximum is
Given:
The ratio of the measures of the three sides of a triangle is .
Its perimeter is 31.4 centimeters
To find:
The shortest side of the triangle.
Solution:
Let the measures of the three sides of a triangle are respectively (in cm).
Its perimeter is 31.4 centimeters.
On further simplification, we get
Divide both sides by 3.
Now, the sides of triangle are
Therefore, the length of the shortest side is 6.978 cm.
